||||
|
||||
## 2025-11-01 - 3.2.0 - feat(StockDataService)
|
||||

|
||||
- Update README with Unified Stock Data API examples, usage, and documentation reflecting new unified service
|
||||
- Minor infra: add .claude/settings.local.json permissions for local tooling and web fetch domains
|
||||
|
||||
## 2025-11-01 - 3.1.0 - feat(fundamentals)
|
||||
Add FundamentalsService and SEC EDGAR provider with caching, rate-limiting, tests, and docs updates
|
||||
|
||||

|
||||
- Expose fundamentals interfaces and services from ts/stocks (exports updated)
|
||||
- Add comprehensive tests for FundamentalsService and SecEdgarProvider (new test files)
|
||||
- Update README with new Fundamentals module documentation, usage examples, and configuration guidance
|
||||
- Implement caching and TTL handling for fundamentals data and provider-specific cache TTL support
|
||||
- Add .claude/settings.local.json (local permissions) and various test improvements
|
||||
|
||||
## 2025-10-31 - 3.0.0 - BREAKING CHANGE(stocks)
|
||||
Unify stock provider API to discriminated IStockDataRequest and add company name/fullname enrichment
|
||||
|
||||
- Replace legacy provider methods (fetchPrice/fetchPrices) with a single fetchData(request: IStockDataRequest) on IStockProvider — providers must be migrated to the new signature.
|
||||
- Migrate StockPriceService to the unified getData(request: IStockDataRequest) API. Convenience helpers getPrice/getPrices now wrap getData.
|
||||
- Add companyName and companyFullName fields to IStockPrice and populate them in provider mappings (Marketstack mapping updated; Yahoo provider updated to support the unified API).
|
||||
- MarketstackProvider: added buildCompanyFullName helper and improved mapping to include company identification fields and full name formatting.
|
||||
- YahooFinanceProvider: updated to implement fetchData and to route current/batch requests through the new unified request types; historical/intraday throw explicit errors.
|
||||
- Updated tests to exercise the new unified API, company-name enrichment, caching behavior, and provider direct methods.
|
||||
- Note: This is a breaking change for external providers and integrations that implemented the old fetchPrice/fetchPrices API. Bump major version.
|
||||
|
||||
## 2025-10-31 - 2.1.0 - feat(stocks)
|
||||
Add unified stock data API (getData) with historical/OHLCV support, smart caching and provider enhancements
|
||||
|
||||
- Introduce discriminated union request types (IStockDataRequest) and a unified getData() method (replaces legacy getPrice/getPrices for new use cases)
|
||||
- Add OHLCV fields (open, high, low, volume, adjusted) and metadata (dataType, fetchedAt) to IStockPrice
|
||||
- Implement data-type aware smart caching with TTLs (historical = never expire, EOD = 24h, live = 30s, intraday matches interval)
|
||||
- Extend StockPriceService: new getData(), data-specific cache keys, cache maxEntries increased (default 10000), and TTL-aware add/get cache logic
|
||||
- Enhance Marketstack provider: unified fetchData(), historical date-range retrieval with pagination, exchange filtering, batch current fetch, OHLCV mapping, and intraday placeholder
|
||||
- Update Yahoo provider to include dataType and fetchedAt (live data) and maintain legacy fetchPrice/fetchPrices compatibility
|
||||
- Add/adjust tests to cover unified API, historical retrieval, OHLCV presence and smart caching behavior; test setup updated to require explicit OpenData directory paths
|
||||
- Update README to document v2.1 changes, migration examples, and new stock provider capabilities
|
||||
|
||||
## 2025-10-31 - 2.0.0 - BREAKING CHANGE(OpenData)
|
||||
Require explicit directory paths for OpenData (nogit/download/germanBusinessData); remove automatic .nogit creation; update HandelsRegister, JsonlDataProcessor, tests and README.
|
||||
|
||||
- Breaking: OpenData constructor now requires a config object with nogitDir, downloadDir and germanBusinessDataDir. The constructor will throw if these paths are not provided.
|
||||
- Removed automatic creation/export of .nogit/download/germanBusinessData from ts/paths. OpenData.start now ensures the required directories exist.
|
||||
- HandelsRegister API changed: constructor now accepts downloadDir and manages its own unique download folder; screenshot and download paths now use the configured downloadDir.
|
||||
- JsonlDataProcessor now accepts a germanBusinessDataDir parameter and uses it when ensuring/storing data instead of relying on global paths.
|
||||
- Updated tests to provide explicit path configuration (tests now set testNogitDir, testDownloadDir, testGermanBusinessDataDir and write outputs accordingly) and to use updated constructors and qenv usage.
|
||||
- Documentation updated (README) to document the breaking change and show examples for required directory configuration when instantiating OpenData.
|
||||
- Added .claude/settings.local.json for local permissions/config used in development/CI environments.
|
||||
|
||||

### 📈 Stock Market Data
|
||||
### ✨ Unified Stock Data API (Recommended)
|
||||
|
||||
Get market data with EOD (End-of-Day) pricing:
|
||||
Get complete stock data with automatic enrichment - the elegant way:
|
||||
|
||||
```typescript
|
||||
import { StockPriceService, MarketstackProvider } from '@fin.cx/opendata';
|
||||
import { StockDataService, YahooFinanceProvider, SecEdgarProvider } from '@fin.cx/opendata';
|
||||
|
||||
// Initialize the service with caching
|
||||
const stockService = new StockPriceService({
|
||||
ttl: 60000, // Cache for 1 minute
|
||||
maxEntries: 1000 // Max cached symbols
|
||||
// Initialize unified service
|
||||
const stockData = new StockDataService();
|
||||
|
||||
// Register providers
|
||||
stockData.registerPriceProvider(new YahooFinanceProvider());
|
||||
stockData.registerFundamentalsProvider(new SecEdgarProvider({
|
||||
userAgent: 'YourCompany youremail@example.com'
|
||||
}));
|
||||
|
||||
// ✨ Get complete stock data with ONE method call
|
||||
const apple = await stockData.getStockData('AAPL');
|
||||
|
||||
console.log({
|
||||
company: apple.fundamentals.companyName, // "Apple Inc."
|
||||
price: apple.price.price, // $270.37
|
||||
marketCap: apple.fundamentals.marketCap, // $4.13T (auto-calculated!)
|
||||
peRatio: apple.fundamentals.priceToEarnings, // 28.42 (auto-calculated!)
|
||||
pbRatio: apple.fundamentals.priceToBook, // 45.12 (auto-calculated!)
|
||||
eps: apple.fundamentals.earningsPerShareDiluted, // $6.13
|
||||
revenue: apple.fundamentals.revenue // $385.6B
|
||||
});
|
||||
|
||||
// Register Marketstack provider with API key
|
||||
stockService.register(new MarketstackProvider('YOUR_API_KEY'), {
|
||||
priority: 100,
|
||||
retryAttempts: 3
|
||||
});
|
||||
// Batch fetch with automatic enrichment
|
||||
const stocks = await stockData.getBatchStockData(['AAPL', 'MSFT', 'GOOGL']);
|
||||
|
||||
// Get single stock price
|
||||
const apple = await stockService.getPrice({ ticker: 'AAPL' });
|
||||
console.log(`Apple: $${apple.price} (${apple.changePercent.toFixed(2)}%)`);
|
||||
|
||||
// Get multiple prices at once (batch fetching)
|
||||
const prices = await stockService.getPrices({
|
||||
tickers: ['AAPL', 'MSFT', 'GOOGL', 'AMZN', 'TSLA']
|
||||
});
|
||||
|
||||
// 125,000+ tickers across 72+ exchanges worldwide
|
||||
const internationalStocks = await stockService.getPrices({
|
||||
tickers: ['AAPL', 'VOD.LON', 'SAP.DEX', 'TM', 'BABA']
|
||||
stocks.forEach(stock => {
|

console.log(`${stock.ticker}: $${stock.price.price.toFixed(2)}, ` +
|
||||
`P/E ${stock.fundamentals?.priceToEarnings?.toFixed(2)}`);

|
||||
// Output:
|

|
||||
- ✅ **Automatic enrichment** - Market cap, P/E, P/B calculated automatically
|
||||
- ✅ **One method call** - No manual `enrichWithPrice()` calls
|
||||
- ✅ **Simplified code** - Less boilerplate, more readable
|
||||
- ✅ **Type-safe** - Full TypeScript support

## Advanced Examples
|
||||
|
||||
### Combined Market Analysis (Unified API)
|
||||
|
||||
Analyze multiple companies with automatic enrichment:
|
||||
|
||||
```typescript
|
||||
import { StockDataService, YahooFinanceProvider, SecEdgarProvider } from '@fin.cx/opendata';
|
||||
|
||||
// Setup unified service
|
||||
const stockData = new StockDataService();
|
||||
stockData.registerPriceProvider(new YahooFinanceProvider());
|
||||
stockData.registerFundamentalsProvider(new SecEdgarProvider({
|
||||
userAgent: 'YourCompany youremail@example.com'
|
||||
}));
|
||||
|
||||
// Analyze multiple companies with ONE call
|
||||
const tickers = ['AAPL', 'MSFT', 'GOOGL', 'AMZN'];
|
||||
const stocks = await stockData.getBatchStockData(tickers);
|
||||
|
||||
// All metrics are automatically calculated!
|
||||
stocks.forEach(stock => {
|
||||
if (stock.fundamentals) {
|
||||
console.log(`\n${stock.fundamentals.companyName} (${stock.ticker})`);
|
||||
console.log(` Price: $${stock.price.price.toFixed(2)}`);
|
||||
console.log(` Market Cap: $${(stock.fundamentals.marketCap! / 1e9).toFixed(2)}B`);
|
||||
console.log(` P/E Ratio: ${stock.fundamentals.priceToEarnings!.toFixed(2)}`);
|
||||
console.log(` Revenue: $${(stock.fundamentals.revenue! / 1e9).toFixed(2)}B`);
|
||||
console.log(` EPS: $${stock.fundamentals.earningsPerShareDiluted!.toFixed(2)}`);
|
||||
}
|
||||
});
|
||||
|
||||
// Or analyze one-by-one with automatic enrichment
|
||||
for (const ticker of tickers) {
|
||||
const stock = await stockData.getStockData(ticker);
|
||||
|
||||
// Everything is already enriched - no manual calculations needed!
|
||||
console.log(`${ticker}: P/E ${stock.fundamentals?.priceToEarnings?.toFixed(2)}`);
|
||||
}
|
||||
```
|
||||
|
||||
### Fundamental Data Screening
|
||||
|
||||
Screen stocks by financial metrics:
|
||||
|
||||
```typescript
|
||||
// Fetch data for multiple tickers
|
||||
const tickers = ['AAPL', 'MSFT', 'GOOGL', 'AMZN', 'META', 'NVDA', 'TSLA'];
|
||||
const stocks = await stockData.getBatchStockData(tickers);
|
||||
|
||||
// Filter by criteria (all metrics auto-calculated!)
|
||||
const valueStocks = stocks.filter(stock => {
|
||||
const f = stock.fundamentals;
|
||||
return f &&
|
||||
f.priceToEarnings! < 30 && // P/E under 30
|
||||
f.priceToBook! < 10 && // P/B under 10
|
||||
f.revenue! > 100_000_000_000; // Revenue > $100B
|
||||
});
|
||||
|
||||
console.log('\n💎 Value Stocks:');
|
||||
valueStocks.forEach(stock => {
|
||||
console.log(`${stock.ticker}: P/E ${stock.fundamentals!.priceToEarnings!.toFixed(2)}, ` +
|
||||
`P/B ${stock.fundamentals!.priceToBook!.toFixed(2)}`);
|
||||
});
|
||||
```
|
||||
|
||||
### Historical Data Analysis
|
||||
|
||||
Fetch and analyze historical price trends:
|
||||
|
||||
```typescript
|
||||
// Get 1 year of historical data
|
||||
const history = await stockService.getData({
|
||||
type: 'historical',
|
||||
ticker: 'AAPL',
|
||||
from: new Date('2024-01-01'),
|
||||
to: new Date('2024-12-31'),
|
||||
sort: 'DESC' // Newest first
|
||||
});
|
||||
|
||||
// Calculate statistics
|
||||
const prices = history.map(p => p.price);
|
||||
const high52Week = Math.max(...prices);
|
||||
const low52Week = Math.min(...prices);
|
||||
const avgPrice = prices.reduce((a, b) => a + b) / prices.length;
|
||||
|
||||
console.log(`52-Week Analysis for AAPL:`);
|
||||
console.log(` High: $${high52Week.toFixed(2)}`);
|
||||
console.log(` Low: $${low52Week.toFixed(2)}`);
|
||||
console.log(` Average: $${avgPrice.toFixed(2)}`);
|
||||
console.log(` Days: ${history.length}`);
|
||||
|
||||
// Calculate Simple Moving Average
|
||||
const calculateSMA = (data: IStockPrice[], period: number) => {
|
||||
const sma: number[] = [];
|
||||
for (let i = period - 1; i < data.length; i++) {
|
||||
const sum = data.slice(i - period + 1, i + 1)
|
||||
.reduce((acc, p) => acc + p.price, 0);
|
||||
sma.push(sum / period);
|
||||
}
|
||||
return sma;
|
||||
};
|
||||

### OHLCV Technical Analysis
|
||||
|
||||
Use OHLCV data for technical indicators:
|
||||
|
||||
```typescript
|
||||
const history = await stockService.getData({
|
||||
type: 'historical',
|
||||
ticker: 'TSLA',
|
||||
from: new Date('2024-11-01'),
|
||||
to: new Date('2024-11-30')
|
||||
});
|
||||
|
||||
// Calculate daily trading range
|
||||
for (const day of history) {
|
||||
const range = day.high! - day.low!;
|
||||
const rangePercent = (range / day.low!) * 100;
|
||||
|
||||
console.log(`${day.timestamp.toISOString().split('T')[0]}:`);
|
||||
console.log(` Open: $${day.open}`);
|
||||
console.log(` High: $${day.high}`);
|
||||
console.log(` Low: $${day.low}`);
|
||||
console.log(` Close: $${day.price}`);
|
||||
console.log(` Volume: ${day.volume?.toLocaleString()}`);
|
||||
console.log(` Range: $${range.toFixed(2)} (${rangePercent.toFixed(2)}%)`);
|
||||
}
|
||||
```
|
||||
|
||||
### Fundamental Data Screening
|
||||
|
||||
Screen stocks based on fundamental metrics:
|
||||
|
||||
```typescript
|
||||
const tickers = ['AAPL', 'MSFT', 'GOOGL', 'AMZN', 'TSLA', 'META', 'NVDA'];
|
||||
|
||||
// Fetch fundamentals for all tickers
|
||||
const allFundamentals = await fundamentalsService.getBatchFundamentals(tickers);
|
||||
|
||||
// Get current prices
|
||||
const prices = await stockService.getData({
|
||||
type: 'batch',
|
||||
tickers: tickers
|
||||
});
|
||||
|
||||
// Create price map
|
||||
const priceMap = new Map(prices.map(p => [p.ticker, p.price]));
|
||||
|
||||
// Enrich with prices
|
||||
const enriched = await fundamentalsService.enrichBatchWithPrices(
|
||||
allFundamentals,
|
||||
priceMap
|
||||
);
|
||||
|
||||
// Screen for value stocks (P/E < 25, P/B < 5)
|
||||
const valueStocks = enriched.filter(f =>
|
||||
f.priceToEarnings && f.priceToEarnings < 25 &&
|
||||
f.priceToBook && f.priceToBook < 5
|
||||
);
|
||||
|
||||
console.log('Value Stocks:');
|
||||
valueStocks.forEach(stock => {
|
||||
console.log(`\n${stock.companyName} (${stock.ticker})`);
|
||||
console.log(` P/E Ratio: ${stock.priceToEarnings!.toFixed(2)}`);
|
||||
console.log(` P/B Ratio: ${stock.priceToBook!.toFixed(2)}`);
|
||||
console.log(` Market Cap: $${(stock.marketCap! / 1e9).toFixed(2)}B`);
|
||||
});
